Semantics. Vera may not be of any sort of notable nobility, but that doesn't mean she doesn't want to try to at least appear like so. I imagine her character something like Mazoga the Orc and Solair of Astora (If only she could be so grossly incandescent!). Vera doesn't really know the proper definition of what a "Knight" is, but she has a general idea and wants to go about it in her own way. With Violence, but for justice, like Mazoga. She's something akin to Solair in that she's a bit nutty and probably too idealistic for you anti-heroic types, but don't be mistaken, she's still a killer. She just tries to do it for great justice. 

So yeah, Vera's not a knight in title, but she's still going to try to be like one in all but name. And I was wondering if Leora would be interested in trying to go along the same path as Vera is.
